Auto Fill Sold-To Party field in ZMCR doesn't work

For ChaRM RfC, I configured ZMCR transaction type.

I want the Sold-To Party field populated automatically. I followed instruction given in some sdn forums:

1. IB52 assign Solution Manager Client 001 to Sold-To Partner ID

2. Partner Determination Procedure > Partner Functions in Procedure: ZMCR0001 was set to 0018 SAP Service: Determination via IBase/Ind. Object from Ref.Object Set (Tried AIC2, AIC3 as well).

Still the Sold-To Party field is not populated automatically after I click Create new Request for Change.

Appreciate your comments and suggestions.

Thank you.

Regards,

Fausto
